A bra made just for cyclists.

Just as cycling equipment benefits from the feedback of the sponsored male racers, the gear used by the growing number of female cyclists reflects the hard-earned knowledge and feedback that pro women can give. The input of ladies sponsored by Castelli has led to this uniquely cycling-specific sports bra, the Castelli Rosso Corsa Light Bra.

Cycling in particular demands slightly different things from a bra than running does. Chest-crushing compression is less of an issue, so the Rosso Corsa Light Bra focuses more on breathability and ventilation. Sport bras can become quite soggy when you're really exerting yourself, and then you're stuck with what feels like a sweaty straightjacket wrapped around you for the duration of the ride. This is a problem (particularly in winter weather) when you're riding over multiple long climbs where you're sweating on the way up and freezing on the way down. This bra has been designed with an ingenious mix of tech fabrics, which are all intended to provide the optimum amount of wicking to keep you comfortable and dry. The sides and back have maximum ventilation with the Tulle Mesh inserts in place to help ventilate.

That is not to say that Castelli has compromised on fit and support. The Rosso Corsa offers gentle support and a comfortable fit. In particular, the cross straps are Giro 3, the same soft, stretchy material and seamless design used in Castelli's top-of-the-line bibs. As a result, you get less stress and fatigue on your shoulders and trapezius muscles on a long, demanding ride.

The Castelli Rosso Corsa Light Bra is available in either Black or White. The bra works best for A/B cups, and comes in five sizes according to the measurement around the rib cage under the bust: X-Small 26-28in, Small 29-30in, Medium 30-32in, Large 32-34in and X-Large 34-36in.

Runs small; returned

Fit: Runs small

Size Bought: medium

Wife really wanted to like this bra...straps...fabric...weight...all was perfect. She is a 34B & ordered a Medium, straps, bottom band all fit perfect. The problem was that the "cups" were so confining she felt she was in a corset from the 1700's that for the first time in her adult life produced cleavage.

Most comfortable bra I ride with

Familiarity: I've used it once or twice and have initial impressions

Fit: True to size

Size Bought: small

Amazingly comfortable. Wore for a 180 mile 2 day ride. I range (depending on brand) from a 32-34D. I got a small based on the band size. Was a little tight but I assume it will stretch over time. Not uncomfortable tight - just left a band mark. The ladies stay tucked in okay and it works more like a compression bra in the front that I like for cycling. I am ordering 2 more and one is going to be a medium just to see the difference with the cup size.

Comfortable Bra

Familiarity: I've used it several times

Fit: True to size

Size Bought: Medium

I am usually 36B so I bought a Medium and it fits perfect, it is very comfortable so you can forget that you are wearing it even after riding more than 5 hours. The downside is that It does not have pads.

Really Comfortable

Familiarity: I've used it once or twice and have initial impressions

My chest measures 33" and I ordered a size small. It's a bit hard to get on but very comfortable once in place. I'm probably between a small and medium so if I get another one, I may try to size up one.

Have an answer for Lorraine M.?

I'm a 32D and I bought both a Small and Medium. I ended up returning the M as it felt too loose in the band, and did not offer enough support while riding, especially when going over bumpy road. The Small fits perfect for me.

I wear mine every ride

Familiarity: I've put it through the wringer

I'm ordering a second one of these. It is so comfy. The flat straps over the shoulders practically disappear, and the chest band is not tight. (I leave that to the heart monitor band!) There is not a lot of support, but enough to keep things in place when going in for that cup of coffee. When riding, how much support do you really need, anyway?

As to size, I'm between a small and a medium, I think. I went with the medium because I wanted to maximize comfort. Maybe if I had gotten a small, it would feel tighter and more supportive. But, I'm sticking with Medium in the order I'm placing now.

Sizes

According to the sizing chart on the site, I should be S or M. I ordered one of each size and both were small. So I'll ask now an L, because it seems an excellent product and I want to try. I think the sizing chart needs to be revised.

Awesome Bra! :)

I put this bra on and felt like I wasn't even wearing a bra...it is seriously that comfortable. Riding with this bra on was completely wonderful. I felt no weight in my chest and no tension in my shoulders from the straps. I didn't even really feel the straps at all. We're given so many reasons why we have certain pains but I've never had anyone suggest wearing the wrong bra while cycling was causing me to have some pain around my neck and shoulders. After wearing this just once I can tell that my bra was the reason to the problems and this bra was perfect the solution. I'm a 32 B and the small fits perfectly for me. I just wish I had lots more money so I could buy more.
